I'm looking for enamel pins featuring a butterfly clip mechanism. The desired shape is round, and the size should range from 2 to 2.5 cm at most. I'm interested in three color options – plain gold, silver, and bronze. I'd like to order 20 pieces of each color, or if that's not feasible, I'm open to a mixed batch totaling 100 pins. Please provide details on pricing and availability, as well as any minimum order requirements or lead times. Thanks!
